Launch balls to mine rock. Spend the resources you dig up on more balls. Explore the underground world and find hidden upgrade points to unlock new balls and strengthen their unique abilities. Unearth golden keys, open chests and drill through sealed rock walls to reveal the ancient cave art buried within.
Features
Explore a vast underground world
Start with a small opening and work your way deeper into the rock. Zoom in to watch the balls break it apart, or zoom out to see the enormous shapes taking form.
Handcrafted cave art, different routes each run
Mammoths, deer, hunters, suns and eyes lie hidden underground, formed from rock walls. Each new run changes which areas are sealed, where natural entrances lead and where treasures are found.
Balls with distinct abilities
Blue directional balls move horizontally or vertically. Red smash balls break the rock around each impact, while green poison balls spread poison from stone to stone. Unlock more ball types and upgrade their abilities.
Find chests and drill through walls
Use golden keys to open money chests for resources to buy more balls, or tool chests for drills that break through walls. Keys are limited. Choose where to make an opening and send your balls into new areas.
Let the balls bounce!
Grow from a single ball to a whole swarm. Watch them ricochet and chip away at the rock, bringing more and more ancient figures back to light.
